| Getting your driver to handle more than one I/O request at a time | Dev Center - Hardware > Docs > Drivers > Driver Lifecycle Fundamentals > Key Driver Concepts > Getting your driver to handle more than one I/O request at a time | After you've opened a device for overlapped I/O, can you simply omit the OVERLAPPED structure to get synchronous I/O? No, you must supply an OVERLAPPED structure for all function calls (read, write, or device control) with that handle. Passing NULL can lead to undefined behavior, even if the driver completes the request synchronously. For synchronous I/O, the OVERLAPPED structure can be declared on the stack as long as the application waits for the I/O to complete before returning.

| System-Defined Device Properties | Dev Center - Hardware > Docs > Drivers > Windows Driver Development > Device and Driver Installation > Design Guide > Device and Driver Installation Advanced Topics > Device Identification and Properties > Device Properties > Unified Device Property Model (Windows Vista and Later) > System-Defined Device Properties | In Windows Vista and later versions of Windows, the unified device property model supports system-defined properties that characterize the configuration or operation of device instances, device setup classes, device interface classes, and device interfaces. Each property is represented by a property key, which is a GUID value that identifies a property category and a property identifier. The system-defined property key categories are reserved for system use only.

In this case, the channel has already been released, so any further calls might cause undefined behavior. This restriction might require coordination between your foreground thread and callback object.
You must make sure that your foreground thread and callback object coordinate the call to CloseChannel and Release. Your foreground thread and your callback object cannot begin a call to CloseChannel if the other is about to call or has completed calling Release. You can implement this restriction by using the InterlockedCompareExchange routine. If you do not use InterlockedCompareExchange, you might cause undefined behavior.

| HwScsiFindAdapter routine | Dev Center - Hardware > Docs > Drivers > Windows Driver Development > Device and Driver Technologies > Storage Devices > Reference > Storage Routines > SCSI Miniport Driver Routines > HwScsiFindAdapter | The port driver is responsible for doing bus-level configuration programming, particularly of dynamically configurable I/O buses with published standard interfaces, such as PCI and PCMCIA. For an HBA on such an I/O bus, the miniport driver can simply accept the interrupt configuration information provided as values reserved for system use. For an HBA on other types of I/O buses, a miniport driver should program its HBA to use any supplied interrupt value if its HBA supports programmable interrupt configuration. If no interrupt configuration is supplied, as indicated either by the value zero or the value SP_UNINITIALIZED_VALUE, the miniport driver should either query its HBA if the HBA supports interrupt selection using jumpers or should supply a nonzero default interrupt configuration unless the HBA does not use interrupts. The miniport driver should set the interrupt configuration value to zero if it controls its HBA in a polled mode.

| MmBuildMdlForNonPagedPool routine | Dev Center - Hardware > Docs > Drivers > Windows Driver Development > Kernel-Mode Driver Architecture > Reference > Driver Support Routines > Memory Manager Routines > MmBuildMdlForNonPagedPool | Because the pages described by the MDL are already nonpageable and are already mapped to the system address space, drivers must not try to lock them by using the MmProbeAndLockPages routine, or to create additional system-address-space mappings by using the MmMapLockedPagesSpecifyCache routine. Similarly, drivers must not try to unlock the pages by using the MmUnlockPages routine, or to release the existing system-address-space mapping by using the MmUnmapLockedPages routine. If a driver performs any of these illegal operations on an MDL that is built by MmBuildMdlForNonPagedPool, the resulting behavior is undefined.

Processor translation buffers cache virtual to physical address translations. These translation buffers allow many virtual addresses to map a single physical address. However, only one caching behavior is allowed for any given physical address translation. Therefore, if a driver maps two different virtual address ranges to the same physical address, it must ensure that it specifies the same caching behavior for both. Otherwise, the processor behavior is undefined with unpredictable system results.

Kernel-Mode Driver Framework converts the WDM IRPs that represent read, write, and device I/O control operations to framework request objects that drivers receive in I/O queues. The framework handles PnP and power management IRPs internally and uses event callback functions to inform the driver of PnP and power events.

| Supporting PnP and Power Management in Software-only Drivers | Dev Center - Hardware > Docs > Drivers > Windows Driver Development > Windows Driver Frameworks > Kernel-Mode Driver Framework > Kernel-Mode Driver Framework Design Guide > PnP and Power Management in Framework-Based Drivers > Supporting PnP and Power Management in Your Driver > Supporting PnP and Power Management in Software-only Drivers | Software-only drivers are drivers that do not access any hardware. Some software-only drivers reside in a driver stack that does not access hardware. Because these drivers do not access hardware, they typically do not have to perform any PnP or power management operations.
Other software-only drivers are filter drivers: they reside in a stack of drivers that do access hardware, but the filter drivers do not access hardware. When a filter driver receives an I/O request that specifies a PnP or power management operation, the driver typically just passes the request to the next driver. The framework intercepts these requests and passes them on, so framework-based drivers never see the requests.
